Just off Seaside this morning. We left PC on 11/9 at 6 pm. Muster drill was promptly at 4pm. Watch video then dial the number - video only lasts a couple minutes. Then you wait for them to call your deck to go to your muster station. Seems to be half the ship first, then the second half of the ship about 10 minutes later. Total took about 30 minutes and we were called with the second half and had to walk down 10 flights of stairs.
Side note - our hotel in Canaveral pre-cruise had a sign announcing a launch on 11/9 at 8:28 pm. We never would have known about it otherwise. We watched from aft deck 16 with probably 100 other people. It was really cool to see a night launch from sea.
